Week 3 - Azkah Anjum “Effervescence”

 Effervescence

(Noun) formation of gas bubbles in a liquid by a chemical reaction

“When the rate of effervescence has slowed considerably, bring the beaker back to your lab station, gently warm the solution with a hot plate (do not boil)” Chemistry lab procedure

When I came across this word on the procedure for a chemistry lab in class, I did not know what observation I was to take note of. I was intrigued by this word because I did not know there was a term that defines the specific bubbles that are produced in a solution when a gas is produced. Now I can use this word to be more precise about the type of bubbles produced in any chemical reaction.

Week 12 - Azkah Anjum “Fetter”

  Fetter (Verb) to restrict or restrain (someone) in an unfair or undesirable fashion “The United States is the world’s best hope, but if you fetter her in the interest through quarrels of the others nations, if you tangle her in the intrigues of Europe, you will destroy her powerful good, and endanger her very existence” (History Primary Source - Henry Lodge’s Stance on League of Nations) When I first read this sentence I did not understand what the speaker meant to convey. I initially thought in this sentence Lodge expressed that the other nations must not exploit the Unites States. After learning the meaning of the word ‘fetter’, I properly understood that Lodge meant to emphasize the harm in restricting the United States rather than accusing the other countries of wrongly take advantage of the United States.

Alex Therrien Week 11 - Hyperbolic Space

Image
 This came out a lot later than I wanted. I forgot about this for a bit. Whoops. Anyways I should be able to catch up on everything. N - A type of non euclidean space where every point has a negative curvature (thing pringle/saddle shaped instead of spherical) The straight lines form hyperbolas in this type of space. This wasn't really much of a vocab word to be honest, but more of an interesting topic I learned about and did a bit of research on to learn more about. Anyways, Hyperbolic space is where every direction of travel is in a hyperbola. Due to this, equilateral triangles have angles of less than 60 degrees, and circles are rather strange. In euclidean geometry, a circle’s circumference is C=2pi*r. This is a linear relationship. However, in hyperbolic space this relationship is hyperbolic (C = 2πsinh(r)). This means that a 2D circle in hyperbolic space would have to be displayed in 3D euclidean space as wrinkled in order to actually fit the extra circumference. This is what...

Emma LaFond Week 9 - Somnambulatory

 Somnambulatory - adj - (figurative) going through the motions "... whereupon Mr. Wolfsheim swallowed a new sentence he was starting and lapsed into a somnambulatory abstraction" (The Great Gatsby pg 69) I chose this word for the week because I liked the way that it sounded and I found it interesting that such a long word had such a simple meaning.
